To all. whom it may concern:

Be it known that .I, RQY.R.I.ROGERS7EQLVClt1- zen of theUnited State s, residing ,atISan. Francisco, lnthe county offlSan Francisco,

State of California, haveinvented aflnew and useful Liquid-Dispenser, of :which the following is .a specification, inlsucha-full an clear terms as willenable those lskilled'in the art to construct and use the same.

This invention relates to a dispensing device for. the receptacle containing liquid soap, or any other liquid, which it may be desired to dispense ,from the;receptacle in small quantities.

An object of the invention is to provide means whereby the dispensing apparatus will deliver only a small predetermined quantity of the fluid with each operation thereof.

Another object of the invention is to produce a dispensing device which is capable of being opened only with a certain key or a suitable instrument intended therefor, there being no projecting parts whereby the closure for the receptacle may be removed by unauthorized persons.

Another object of the invention is to provide means whereby the passage ways of the casing and of the plunger will be kept free, the inlet into the casing being of such a size with respect to the size of the openings in the plunger and outlet end of the casing as to always cause a forcible motion of the fluid through all of said openings thereby preventing hard particles from filling them up.

l/Vhile the closure for the receptacle has been shown in connection with a spherical soap holder it will be understood by those skilled in the art that this closure may be applied to any liquid receptacle. The closure will not allow leakage or escape of liquid from the receptacle at any time except when the device is operated to secure the intermittent discharge of said liquid.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof,

Figure 1 is a vertical sectional view through the liquid receptacle and the closure for the mouth of the same, the fixture for securing the receptacle to a wall or stand being shown in full lines,

Fig. 2 is a bottom plan view of the closure for the receptacle and the receptacle support melting inthedirection of thearrow Fig 1, anc

Fig. 3 is a .side elevationofa slightly modified form of the dispensing device pro vided. with a resilient gasket v for i holding it iirthel mouth of a bottle;orcan special fittings being thus dispensed with, V v I The numeral 1 indicates the wall sto which the fixture 3 ,is securec l l by. means of suitablescrews Thefiritur ha s an apm 5 -.W- h a eake o e e vl g :PlFQJ Q Il arin 6 of the ring 7 in which the liquid receptacle :is. placed. The armg6l-is connected with-the arm 5 detachably by means of a suitable screw 8. The liquid receptacle in this instance is spherical and is indicated at 9 and is secured to the ring 7 by being secured thereinto with a suitable cement so that it is permanently connected with the ring 7.

[he bottom flange of the ring 7 is threaded as indicated at 10 to receive a flanged closure plug 11. The plug 11 has a cylindrical portion 12 which extends up into the receptacle and which is provided with an opening 13 for the ingress thereinto of the liquid and for the passage backward and upward of air from the atmosphere into the receptacle. \Vithin the cylinder 12 there is a plunger 14 having a suitable number of holes 15 extending therethrough and having a rod 16 connected therewith which has a knob on its lower end for the user to raise the plunger with.

The plunger 14 is held normally seated against the gasket 17 by means of a suitable spring 18, which spring is held against the plunger by means of a closure 19 screwed into the upper end of the cylinder 12, although the device will operate successfully without the spring.

The operation of the apparatus is as follows: Assuming the receptacle to be filled with liquid, the spring 18 and the Weight of the plunger will normally hold the plunger seated on its gasket, whereupon some of the liquid will pass into the cylinder 12 through the small opening therein. \Vhen the person desiring to make use of the liquid raises the plunger some of the liquid will be forced back through the open ing 13 while some of it will be forced through the openings 15 in the plunger and will therefore fall out into the hand of the user.

In Fig. 3 there is shown a slightly modified form of the invention in which 20 indicates the cylinder of the dispenser which is integral with the flange 21. The cylinder is closed with a cap 22 and has a small opening for the ingress of liquid as indicated at 23, said opening allowing the air to enter the receptacle when a small amount of liquid has been withdrawn therefrom. The cylinder 20 is surrounded with a suitable cork or rubber gasket 24: which enables the dispenser to be secured in the mouth of a given receptacle. The plunger is operated by the rod 25.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, express reservation being made of permissible modifications:

A liquid dispenser comprising a receptacle, a closure removably secured in the mouth of the receptacle, said closure having a chamber with a single inlet opening and a larger outlet, a removable plug forming a closure for one end of said chamber, a solid piston in contact with the chamber walls and having passages to allow the liquid to pass from one end to the other end thereof, the sizes of the several openings being such that a portion of the liquid will be forced back into the receptacle on each operation of the plunger, a spring to seat the piston, and an operating rod connected with the piston and extending through the chamber outlet, the rod being smaller than said outlet to allow the liquid to escape.

In testimony whereof I have hereunto set my hand this 26 day of October, A, D. 1915.

ROY R. ROGERS.
